SOFT-FACE HAMMER.

Application filed July 25,

This invention relates more particularly to improvements in the manufacture of hammers, provided with a relatively soft striking face, so that they may be used upon and about machinery without injuring the surfaces struck thereby. Hammers of this character have been made with faces of various materials such as lead, rubber and rawhide, but, ordinarily, rawhide is preferred. In any case, particularly when rawhide or'the like is used, I have found it desirable to provide for readily replacing a worn face. I

The primary object, therefore, of the present improvement is to provide a hammer with striking faces of rawhide or other suit-- able relatively soft materiah'which may be readily renewed when worn out or battered down to such an extent as to require replacement.

In the present instance, the rawhide face members are preferably formed by rolling a strip of rawhide to the desired diameter and inserting it as a plug in a socket or recess in the end of the hammer head. Continued use of this type of hammer ultimately wears down the rawhide or soft material striking face, and the plug of rawhide or the like becomes so battered that a new striking face is required lVith ordinary types of rawhide hammers, there is no convenient arrangement or means for renewing battered down or worn striking faces, and when a hammer becomes so badily worn as to require replacement, a complete new hammer must be procured.

In the present instance, a further object is to provide a suitable wedging member, mounted in the socket or recess of the hammer head, and arranged so as to be readily forced out or removed therefrom, when it is desired to renew the rawhide str iking face of the hammer. My improved wedging member preferably comprises a disc of sheet metal provided with a plurality of prongs or wedges adapted to enter the relatively soft material of the rawhide or the like face member, so as to wedge the material of the latter into close frictional engagement with the walls of the socket or recess, to thereby retain the soft face member in place. In this connection, it will be understood that in using my type of hammer, continual hammering with the face thereof will 1927. Serial No. 208,224.

seat the face member more firmly on the wedging prongs. Obviously, this is desirable, particularly whcn rawhide is used, for the latter is subject to shrinkage and the continued hammering enables the wedging action to take up any shrinkage and continue to retain the plug-like face member in the socket or recess of the hammer head.

By mounting the wedging member loosely in the bottom of the socket or recess in the hammer head, .as in the present instance, and providing a hole or suitable opening in the head, communicating with the bottom of the recess, through which a rod or other device may be inserted, the renewal of a worn out striking face member is facilitated. Thus, by hammering or otherwise thrusting a rod or suitable device against the wedging member, the latter, with the striking face member, can be forced or driven out of the socket or recess, after which a. new striking face member may be forced into the socket, to be secured therein by the wedging member, as previously described.

In order to illustrate my improvement, one form thereof is shown in the accompanying drawings, in which'Fig. 1 is a perspective view of the complete hammer; Fig. 2 is a transverse section thereof, with a dotted indication of the removal of one striking face; Fig. 3 is an end or face view of the hammer, and Fig. 4c is a perspective of the wedging member.

Referring to the drawings, it will be seen i that the head A of the hammer, which may be formed of cast iron or other suitable material, 1s provided with the usual handle B.

In the present instance, the hammer head A is substantially cylindrical and is preferably provided at each end with a cylindrical socket or recess C, formed by annular flanges D, integral with or otherwise secured to the head A, as seen more particularly in Figs. 2 and 3 of the drawings. In the present instance, I mount in the recess or sockets C, striking face members E, of relatively soft material, which in the present instance, are preferably coils of rawhide, each formed from spirally rolling rawhide strips F, as more particularly shown in Fig. 3; In rolling the rawhide strips F, for forming the rawhide striking face members E, care should be exercised to see that the face members or rawhide plugs, when finished are of a diameter permitting them to be readily inserted in the sockets or, recesses C without much plav.

In or r to firmly secure the rawhide strikingface members E in the sockets C, a wedging member G is preferably mounted in the bottom of the socket 0r recess,,as,will be seen in Fig. 2. The wedging inember G is preferably formed v as a. .;disc .or ,plate, of

sheet metal, of suitable size, shape and thick- ,ness,,having .a plurality of. .upwardly or outwardly pro ecting wedges or prongs H, ,ada ated to penetrate the relatlvely soft material of the face inember E, and force the J latter into firm, frictional engagement with the inner wall of the recess C. It will be understood.that thiswedging member may beinade in any. suitable 'or. preferred manner M1161 and communicating.with the recessesrC throughthe bottoms'th'ereof, so: that a ro'd L, tool, or other suitable. device may be brought into contact with the Wedgingmemat -M, down to the bottoms of; the

and is preferably mounted in thesocket or vrecessess C, ,so that'the prongs .or wedges H .will be in position to.properly engage the rear ends of the plug-like face members.

An mportant feature,. however, of the PZGSGFHUilHPFOVGlTlQZIt is that the wedging membersG are removably placed or; loosely mounted lnthesockets .and. held in place 1) Y the striking face members which the O wedge in the sockets. The head A of'the hammer- 1s preferably provlded =W1tl1 notches or openings K, formed 111 any suitable manher G, whereby the latter, together withthe striking face, inay, be.;driven .or forced out of the socket or recess. This, arrangement .is inoreparticularly indicatedI in'Fig. 2 of the drawings, which shows in dotted lines, the r0d- L,-passing through one. of the openings at. K to force out, thewedging members G and the associated face member E, as'represented by the dotted line positions thereof. In the present form of my improvement the sides of the head-of the hammer arelcut away sockets or recesses C, so as to produee'the openings K. {Elie dotted lines in Fig.3, represent the walls -M of, the transverse cuts on thezhamner head and outline the openings.
